Because of the recent transformation of the market, Quore, Inc., must increase productivity 10 percent over the course of the next two years, or it will certainly go bankrupt. In fact, however, Quore's production structure is such that if a 10 percent productivity increase is possible, then a 20 percent increase is attainable. If the statements above are true, which one of the following must on the basis of them also be true? I diagrammed each of the answer choices. I ultimately chose answer choice 'B" because it seemed to validate the premises and indicated that it must be true. While, I understand why 'E' is the correct answer, I was hoping you could share why 'B' is not correct.
